John Bennett (fl. 1760-d. 1787) was a London printer best known for his role in the successful partnership of Sayer & Bennett. In 1760, Bennett became a servant of Robert Sayer (ca. 1724-1794), the prominent print and map seller, and was apprenticed to him in 1765. In 1774, Bennett became a free journeyman and entered into a partnership with Sayer. They issued joint advertisements and publications. In 1777, Bennett owned 1/3 share in the business. The partnership was likely to continue fruitfully, but in 1781 Bennett began to show signs of mental illness. In 1783, he was admitted to an asylum for nine months and, in 1784, Sayer filed papers to dissolve their business partnership. Bennett died in 1787.
